marusya05 [52]

The reason that the elasticity of demand is 0.62 for business and 0.12 for economy is because the economy class is more elastic than that of the business.

When the flight ticket of those flying business class is raised, they would not be affected much because they are rich and can afford it. They do not care much about the raise in price.

g Builtrite has calculated the average cash flow to be $16,000 with a standard deviation of $4000. What is the probability of a
Ganezh [65]

Answer:

89.44%

Explanation:

As we know that:

Z = (Cash Flow - Mean) / Standard Deviation

Here

Cash flow is the observed value which is the lower limit here and is $11,000

Mean is the average value of the sample and is $16,000

Standard Deviation is $4,000

By putting values, we have:

Z = ($11,000 - $16,000) / $4,000

= -1.25

The Z value lower than -1.25 is 0.1056 or 10.56%

This means that the probability of cash flow lower than $11,000 is 10.56% and the probability of cash flow greater than $11,000 will be

Probability of cash flow = (1- 0.1056) = 0.8944  which is 89.44%
